Ataui Deng, a Sudanese model who has lived and worked in New York since 2008, has gone missing. On Monday afternoon fashion and entertainment industry insiders, like fellow model Ajak Deng--who appeared in a Benetton spread with Deng--and Deng's friend (and onetime Top Chef contestant) Roblé Ali, asked via Instagram for the public's help locating the model.

On Thursday, May 15, 18-year old Aidan Norvez had just finished an AP Econ exam, one of the last tests of his high school career, and he headed to Central Park with his friends to celebrate. But Norvez, who is scheduled to graduate one month from now, never came home from the park.

The teenager is a type 1, insulin-dependent diabetic, and his family believes he was not wearing his medic alert bracelet on Thursday. He did not have his phone with him either.

Twenty-nine-year-old Jiwon Lee, a standout student in her final year at Columbia University's College of Dental Medicine, disappeared on Tuesday. She was last seen leaving her Upper West Side apartment; according to her family, Lee's phone registered a signal from Washington Heights before going dark.

The search for missing autistic boy Avonte Oquendo came to a heartbreaking end in January, when his remains were found near Powell Cove Boulevard in Queens. A new report released yesterday by the agency in charge of investigating New York City's public schools shows several blunders in Avonte's care and supervision. The most serious -- the one that's likely to come up in the lawsuit she is pursuing against the city -- is that Avonte's mother, Vanessa Fontaine, warned his teacher at his Long Island City special education program that Avonte was likely to run. She requested one-on-one supervision for the boy, which the program at Riverview School, also known as P 277, did not provide. In addition, Avonte's teacher didn't inform school administrators that he was likely to try to leave the building.

According to their report, the Special Commissioner of Investigation for New York City Schools (SCI), headed by Commissioner Richard J. Condon, got involved with Avonte's case on October 7, 2013, four days after he was reported missing, after the NYPD was already searching for the boy.

SCI investigators met with Principal Susan McNulty and Assistant Principal Angela Pomo, who told them that Riverview shares a campus with two other schools, a middle school and a high school, the Academy for Careers in Television and Film. They told SCI investigators that as soon as Avonte was noticed to be missing, at 12:45 p.m., they asked the high school principal, Edgar Rodriguez, who's in charge of the building, to put the entire building on "soft lockdown" so a better search could be conducted. Rodriguez refused, on the grounds that it would "alarm" his students.

James "Jay" Ott was first reported missing on Monday when he failed to show up at the Dock Group, the fashion investment firm where he is a design director.

Ott's friends have spent the last several days distressed, canvassing the city with fliers, desperately seeking any information that may shed light on the Brooklyn fashion designer's disappearance Saturday.

Update, 11:30 a.m.: NYPD officers have determined that the young man photographed on the train is not Avonte Oquendo.

Sergeant Jessica McRorie of the NYPD tells us the teen in the photograph "came into an NYPD precinct with his mother and was interviewed. We've determined that the person in the picture was not Avonte."

She was unable to comment on whether or not the NYPD would continue scaling down its search for the missing teenager, as officials suggested earlier this week. She added only, "The search for Avonte continues."

It's been two weeks since the start of Banksy's residency, and New York City has had the privilege of playing along with one of the most famous artists of our time. We run from borough to borough for the chance to ogle his latest creation before someone defaces it or starts collecting cash from onlookers.

But let's hang on a minute: There are other things that need finding, too. Like human beings. 14-year-old Avonte Oquendo went missing October 4 when he walked out of The Center Boulevard School in Long Island City. One man, who was among the crowd at Banksy's Gladiator piece in Woodside, took the chance to remind the audience that maybe they should syphon just a little bit of their enthusiasm for Banksy into finding Avonte (ed. Or any other missing child for that matter. There are over 800,000 missing children in the U.S. at last count.) Runnin' Scared has video of the scene, after the jump.

The Suffolk County Police Department has issued a Silver Alert for an 87-year-old man suffering from dementia. Medio Figliolia was last seen standing in his driveway of his house at 8 Southhaven Avenue, Mastic, in the early morning on September 18. He was reported missing the night of September 19.

The video above (compliments of NBC New York) is of a press conference held by NYPD Commissioner Ray Kelly regarding the arrest of a suspect in the 1979 disappearance of 6-year-old Etan Patz.

The suspect has been identified as Pedro Hernandez, 51, who was arrested yesterday in Camden, New Jersey. Kelly says Hernandez made statements to police implicating himself in Patz's disappearance -- he says Hernandez used candy to lure the boy into a bodega where he worked. He then attacked him, choking the 6-year-old to death before throwing the remains in the garbage.
